Which GPS device type typically offers an accuracy of 0.5 to 2 meters?

Mapping grade GPS devices are designed to provide higher accuracy than consumer-grade units but do not reach the precision of survey-grade or military-grade devices. They typically offer an accuracy range of 0.5 to 2 meters, making them suitable for tasks such as land-use mapping, basic geolocation services, and some types of engineering applications. This accuracy is achieved through advanced satellite signal processing and may incorporate differential GPS (DGPS) corrections to enhance location precision.

Consumer-grade devices usually have a much lower accuracy, often in the range of 5 to 10 meters, depending on environmental conditions and the number of satellites available. Military-grade devices, on the other hand, offer accuracies of less than a meter and are equipped with advanced technology to avoid errors and provide robust performance in various environments. Survey-grade GPS units provide the highest level of accuracy, often within centimeters, making them ideal for surveying and precise engineering tasks. Thus, mapping grade is the correct answer for devices with an accuracy of 0.5 to 2 meters.
